FIG. 6 is a perspective view of the power storage device 100 as seen from the upper right rear side with the rear door 6 removed.
　蓄電装置１００は、筐体１と、筐体１の前面を形成し、下方を回転軸として筐体１の本体に対して回動可能な前面扉２と、筐体１の背面を形成し、筐体１の本体に対して着脱可能に設けられる背面扉６を備える。この筐体１は、ほぼ直方体であるシンプルな箱型の筐体である。また、設置スペースを有効利用できるように、蓄電装置１００はローボードスタイルとし、上面を平坦なフリースペースとしている。 The power storage device 100 forms a housing 1 and a front surface of the housing 1, and forms a front door 2 that can rotate with respect to the main body of the housing 1 with a lower axis as a rotation axis, and a back surface of the housing 1. A back door 6 is provided that is detachably attached to the main body of the housing 1. The housing 1 is a simple box-shaped housing that is a substantially rectangular parallelepiped. In order to effectively use the installation space, the power storage device 100 has a low board style and a flat free space on the upper surface.
　筐体１の左右側面にはそれぞれ、上下方向に三つ配列された排気口１Ａが設けられる（図１、図４）。筐体本体１の下面の四隅には、蓄電装置１００を容易に移動可能とするキャスター３が設けられる。 The left and right side surfaces of the housing 1 are each provided with three exhaust ports 1A arranged in the vertical direction (FIGS. 1 and 4). Casters 3 are provided at the four corners of the lower surface of the housing body 1 so that the power storage device 100 can be easily moved.
　筐体１の内部には、前方から見て左側に収納棚であるラック５Ａ、右側にラック５Ｂが配置されている（図２）。ラック５Ａには下方から順に、蓄電池ユニット１０Ｂ、１０Ａ及びインバータ４０が収納される。また、ラック５Ｂには下方から順に、蓄電池ユニット１０Ｃ、保護ユニット２０及びＰＭＵ（Power　Management　Unit）３０が収納され、ＰＭＵ３０の上方にはさらに台座５Ｂ１が固定される。台座５Ｂ１上に前方から見て左側にＡＣ／ＤＣコンバータ５０が、右側にＡＣ／ＤＣコンバータ６０が載置される。 Inside the housing 1, a rack 5A, which is a storage shelf, is arranged on the left side when viewed from the front, and a rack 5B is arranged on the right side (FIG. 2). In the rack 5A, storage battery units 10B and 10A and an inverter 40 are accommodated in order from the bottom. Further, in the rack 5B, a storage battery unit 10C, a protection unit 20 and a PMU (Power Management Unit) 30 are accommodated in order from below, and a pedestal 5B1 is further fixed above the PMU 30. On the pedestal 5B1, the AC / DC converter 50 is mounted on the left side and the AC / DC converter 60 is mounted on the right side as viewed from the front.
　また、筐体本体１内部の左右側面それぞれには、排気口１Ａに対応する位置に上下方向に三つ配列されてファンＦ（図３）が設けられる。ファンＦの駆動により、背面扉６に設けられた吸気口６Ｃから吸気され、両側面の排気口１Ａから外部へ排気される。これにより、特に発熱量の高い蓄電池ユニット１０Ａ～１０Ｃによる筐体本体１内部の温度上昇を抑えることができる。 Further, on each of the left and right side surfaces inside the casing body 1, three fans F (FIG. 3) are provided in the vertical direction at positions corresponding to the exhaust ports 1A. By driving the fan F, air is sucked from an air inlet 6C provided in the rear door 6, and is exhausted to the outside from the exhaust ports 1A on both side surfaces. As a result, a rise in temperature inside the casing body 1 due to the storage battery units 10A to 10C having particularly high calorific values can be suppressed.
　次に、筐体１内部に収められる各ユニットにより形成される電気回路について説明する。図７は、蓄電装置１００を組み込んだ表示システム２００の構成を示すブロック図である。表示システム２００は、蓄電装置１００と、太陽電池１２０と、照度センサー１３０Ａ～１３０Ｅと、表示装置１４０から成る。本表示システム２００は、太陽電池１２０、照度センサー１３０Ａ～１３０Ｅ及び表示装置１４０は、公園、公共交通機関の停留所及び駅、商業施設、官公庁施設、病院等の屋外又は公共空間に設置し、蓄電装置１００は、表示装置１４０等から離れた屋内に設置する、といった使用方法を想定している。 Next, an electric circuit formed by each unit housed in the housing 1 will be described. FIG. 7 is a block diagram illustrating a configuration of a display system 200 in which the power storage device 100 is incorporated. Display system 200 includes power storage device 100, solar battery 120, illuminance sensors 130 </ b> A to 130 </ b> E, and display device 140. The display system 200 includes a solar battery 120, illuminance sensors 130A to 130E, and a display device 140 that are installed outdoors or in public spaces such as parks, public transportation stops and stations, commercial facilities, government office facilities, hospitals, etc. 100 assumes a usage method such as installing indoors away from the display device 140 or the like.
　図７においては、上述した蓄電池ユニット１０Ａ～１０Ｃをまとめてバッテリ１０として示している。また、ＡＣ／ＤＣコンバータ６０には、商用交流電源１１０が接続される。 In FIG. 7, the storage battery units 10A to 10C described above are collectively shown as a battery 10. The AC / DC converter 60 is connected to a commercial AC power supply 110.
　ＰＭＵ３０は、充電回路３０１と、制御部３０２と、第１スイッチＳＷ１と、第２スイッチＳＷ２と、第３スイッチＳＷ３と、第４スイッチＳＷ４と、第５スイッチＳＷ５を有している。第１スイッチＳＷ１～第５スイッチＳＷ５は、例えばＭＯＳトランジスタで構成されるスイッチ素子である。 The PMU 30 includes a charging circuit 301, a control unit 302, a first switch SW1, a second switch SW2, a third switch SW3, a fourth switch SW4, and a fifth switch SW5. The first switch SW1 to the fifth switch SW5 are switch elements composed of, for example, MOS transistors.
　第１スイッチＳＷ１は、太陽電池１２０から充電回路３０１への電力供給または遮断を切替える。第２スイッチＳＷ２は、充電回路３０１からバッテリ１０への電力供給または遮断を切替える。第３スイッチＳＷ３は、バッテリ１０から表示装置１４０が接続されるインバータ４０への電力供給または遮断を切替える。第４スイッチＳＷ４は、商用交流電源１１０が接続されるＡＣ／ＤＣコンバータ６０から充電回路３０１への電力供給または遮断を切替える。第５スイッチＳＷ５は、ＡＣ／ＤＣコンバータ６０からインバータ４０への電力供給または遮断を切替える。 1st switch SW1 switches the electric power supply from the solar cell 120 to the charging circuit 301, or interruption | blocking. The second switch SW2 switches power supply or interruption from the charging circuit 301 to the battery 10. The third switch SW3 switches power supply or interruption from the battery 10 to the inverter 40 to which the display device 140 is connected. The fourth switch SW4 switches power supply or interruption from the AC / DC converter 60 to which the commercial AC power supply 110 is connected to the charging circuit 301. The fifth switch SW5 switches power supply or interruption from the AC / DC converter 60 to the inverter 40.
　太陽電池１２０は、太陽光を受けて発電し、発電した直流電力を第１スイッチＳＷ１を介して充電回路３０１に供給する。ＡＣ／ＤＣコンバータ６０は、商用交流電源１１０から供給される交流電力を直流電力に変換し、直流電力を第４スイッチＳＷ４を介して充電回路３０１に供給する。 The solar cell 120 receives sunlight to generate electric power, and supplies the generated DC power to the charging circuit 301 via the first switch SW1. The AC / DC converter 60 converts AC power supplied from the commercial AC power supply 110 into DC power, and supplies the DC power to the charging circuit 301 via the fourth switch SW4.
　充電回路３０１は、太陽電池１２０またはＡＣ／ＤＣコンバータ６０から供給される直流電力を第２スイッチＳＷ２及び保護ユニット２０を介してバッテリ１０に充電する。保護ユニット２０は、バッテリ１０の過充電状態、過放電状態等を検知すると、バッテリ１０を電力ラインから遮断してバッテリ１０を保護する機能を有する。バッテリ１０を構成する蓄電池ユニット１０Ａ～１０Ｃは、それぞれ例えば複数本のリチウムイオン電池から構成される。 The charging circuit 301 charges the battery 10 with the DC power supplied from the solar battery 120 or the AC / DC converter 60 via the second switch SW2 and the protection unit 20. The protection unit 20 has a function of protecting the battery 10 by cutting off the battery 10 from the power line when detecting an overcharged state, an overdischarged state, or the like of the battery 10. Each of the storage battery units 10A to 10C constituting the battery 10 is composed of, for example, a plurality of lithium ion batteries.
　バッテリ１０に充電された直流電力は、保護ユニット２０及び第３スイッチＳＷ３を介してインバータ４０に放電される。また、充電回路３０１が出力する直流電力は、第２スイッチＳＷ２、保護ユニット２０及び第３スイッチＳＷ３を介してインバータ４０に供給される。 DC power charged in the battery 10 is discharged to the inverter 40 through the protection unit 20 and the third switch SW3. Further, the DC power output from the charging circuit 301 is supplied to the inverter 40 via the second switch SW2, the protection unit 20, and the third switch SW3.
　インバータ４０は、供給された直流電力を交流電力に変換し、交流電力を負荷としての表示装置１４０に供給する。表示装置１４０は、例えば液晶表示装置であり、例えば広告情報、ニュース及び交通機関情報などの各種情報を表示する。また、インバータ４０は、後述するコンセントに接続された様々な外部機器に電力供給できる。 The inverter 40 converts the supplied DC power into AC power and supplies the AC power to the display device 140 as a load. The display device 140 is, for example, a liquid crystal display device, and displays various information such as advertisement information, news, and transportation information. Further, the inverter 40 can supply power to various external devices connected to an outlet described later.
　また、ＡＣ／ＤＣコンバータ６０が出力する直流電力は、第５スイッチＳＷ５を介して直接的にインバータ４０に供給することもできる。 Also, the DC power output from the AC / DC converter 60 can be directly supplied to the inverter 40 via the fifth switch SW5.
　インバータ４０からの交流電力はＡＣ／ＤＣコンバータ５０にも入力され、ＡＣ／ＤＣコンバータ５０により変換されて生成された直流電力はファンＦに供給される。また、外部の装置に対し直流電力を供給すべく、蓄電装置１００の外部へ取り出すこともできる。なお、一例としてファンＦを駆動させる場合は、ＡＣ／ＤＣコンバータ５０の出力をファンＦへ供給し、ファンＦを駆動させない場合は、ＡＣ／ＤＣコンバータ５０の出力をファンＦへ供給しない、といった制御を行う。 AC power from the inverter 40 is also input to the AC / DC converter 50, and DC power generated by conversion by the AC / DC converter 50 is supplied to the fan F. Further, it can be taken out of the power storage device 100 in order to supply DC power to an external device. As an example, when the fan F is driven, the output of the AC / DC converter 50 is supplied to the fan F, and when the fan F is not driven, the output of the AC / DC converter 50 is not supplied to the fan F. I do.
　外光の照度を検出する五つの照度センサー１３０Ａ～１３０Ｅは、太陽電池１２０の近傍に設けられ、検出した照度情報を制御部３０２に送る。制御部３０２は、例えばマイコンで構成され、照度センサー１３０Ａ～１３０Ｅからの照度情報及びバッテリ１０からの残容量情報に基づいて第１スイッチＳＷ１～第５スイッチＳＷ５をオンオフ制御する。 The five illuminance sensors 130A to 130E that detect the illuminance of external light are provided in the vicinity of the solar cell 120 and send detected illuminance information to the control unit 302. The control unit 302 includes, for example, a microcomputer, and controls the first switch SW1 to the fifth switch SW5 on and off based on the illuminance information from the illuminance sensors 130A to 130E and the remaining capacity information from the battery 10.
　このように照度センサーの出力を用いて各スイッチを切替える構成を採ることで、太陽電池からの出力電流等を監視して切替える構成よりもシンプルな構成でのスイッチ制御が可能となる。 By adopting a configuration in which each switch is switched using the output of the illuminance sensor in this way, switch control with a simpler configuration than the configuration in which the output current from the solar cell is monitored and switched is possible.
　以上のような表示システム２００であれば、例えば、太陽電池１２０や商用交流電源１１０を用いてバッテリ１０に充電し、災害などで突然停電が発生した場合に、表示装置１４０やインバータ４０に接続された様々な外部機器に緊急電源を供給できる。 In the case of the display system 200 as described above, for example, when the battery 10 is charged using the solar battery 120 or the commercial AC power supply 110 and a power failure occurs suddenly due to a disaster or the like, it is connected to the display device 140 or the inverter 40. Emergency power can be supplied to various external devices.
　また、例えば、日常的にも、夜間に商用交流電源１１０により電力をバッテリ１０に充電しておき、昼間の電力ピーク時に太陽電池１２０及びバッテリ１０を用いて電力供給し、ピーク時電力の削減及び電力料金の削減を図ることができる。 In addition, for example, the battery 10 is charged with the commercial AC power supply 110 at night, and is supplied using the solar cell 120 and the battery 10 at the daytime power peak. Electricity charges can be reduced.

A hole extending in the vertical direction is formed in the link member 4B. A locking portion is formed at the upper end of the hole. The other end of the link member 4A, one end of which is fixed to the front door 2 so as to be rotatable, is fixed to the link member 4B so as to be slidable and rotatable within the hole.
　開いた状態の前面扉２を閉める方向に回動させると、リンク部材４Ａの一端がリンク部材４Ｂの孔部内を上方向に摺動してゆき、前面扉２を完全に閉めるとリンク部材４Ａの一端はリンク部材４Ｂの係止部に係止される。 When the opened front door 2 is rotated in the closing direction, one end of the link member 4A slides upward in the hole of the link member 4B, and when the front door 2 is completely closed, the link member 4A One end is locked to the locking portion of the link member 4B.
＜背面扉の構造について＞
　次に、背面扉６に関する構造について詳細に説明する。背面扉６の裏面側（背面扉６を筐体本体１に取り付けたときの筐体本体１側）を上方斜めから見た斜視図を図８に示す（なお、後述する配線板は取り付けていない状態を示す）。また、背面扉６の表面側（裏面側の反対側）を正面から見た図を図９に示す。 <About the structure of the rear door>
Next, the structure regarding the rear door 6 will be described in detail. FIG. 8 is a perspective view of the rear side of the rear door 6 (the case main body 1 side when the rear door 6 is attached to the case main body 1) as viewed obliquely from above (a wiring board to be described later is not attached). Status). Moreover, the figure which looked at the surface side (opposite side of a back surface side) of the back door 6 from the front is shown in FIG.
　背面扉６の長手方向に延びる一辺の近傍には二つのキーロック部６Ａが間隔をあけて設けられる。また、キーロック部６Ａが設けられる側の一辺と対向する一辺の近傍には、長手方向中央部に一つのキーロック部６Ｂが設けられる。キーロック部６Ａ及び６Ｂは、背面扉６の表面側からキーを差し込んでキーを回動させることにより回動する。 In the vicinity of one side extending in the longitudinal direction of the back door 6, two key lock portions 6A are provided with an interval. Moreover, one key lock part 6B is provided in the center part of a longitudinal direction in the vicinity of one side facing one side where the key lock part 6A is provided. The key lock portions 6A and 6B are rotated by inserting a key from the front side of the rear door 6 and rotating the key.
　また、キーロック部６Ｂ側の長手方向に沿って二つの吸気口６Ｃが配列されて設けられる。片方の吸気口６Ｃより外側に隣接して、表面側から裏面側へ凹んだ配線板取り付け面６Ｄが形成される。配線板取り付け面６Ｄには各種コネクタ用の孔部６Ｄ１が形成される。裏面側から配線板取り付け面６Ｄに配線板が取り付けられることにより、配線板に設けられる照度センサー用コネクタ７１、ＤＣ出力用コネクタ７２、ＲＳ－４８５コネクタ７３及び太陽電池用コネクタ７４が孔部６Ｄ１を通して表面側に突出する（図９）。 Also, two intake ports 6C are arranged along the longitudinal direction on the key lock portion 6B side. A wiring board mounting surface 6D that is recessed from the front surface side to the back surface side is formed adjacent to the outside from one of the intake ports 6C. Holes 6D1 for various connectors are formed on the wiring board mounting surface 6D. By attaching the wiring board to the wiring board attachment surface 6D from the back side, the illuminance sensor connector 71, the DC output connector 72, the RS-485 connector 73, and the solar cell connector 74 provided on the wiring board pass through the hole 6D1. It protrudes to the surface side (FIG. 9).
　照度センサー用コネクタ７１は、照度センサー１３０Ａ～１３０Ｅ（図７）を接続するためのコネクタである。ＤＣ出力用コネクタ７２は、ＡＣ／ＤＣコンバータ５０（図７）の直流出力を蓄電池装置１００外部へ取り出すためのコネクタである。ＤＣ出力用コネクタ７２は、表示装置１４０（図７）を冷却するためのファンを駆動するのに用いられる。ＲＳ－４８５コネクタ７３は、外部のＰＣを接続するためのコネクタであり、接続によりＰＭＵ３０から動作状態をＰＣへ通知するなどができる。太陽電池用コネクタ７４は、太陽電池１２０（図７）を接続するためのコネクタである。 The illuminance sensor connector 71 is a connector for connecting the illuminance sensors 130A to 130E (FIG. 7). The DC output connector 72 is a connector for taking out the DC output of the AC / DC converter 50 (FIG. 7) to the outside of the storage battery device 100. The DC output connector 72 is used to drive a fan for cooling the display device 140 (FIG. 7). The RS-485 connector 73 is a connector for connecting an external PC, and the connection can notify the PC of the operation state from the PMU 30. The solar cell connector 74 is a connector for connecting the solar cell 120 (FIG. 7).
　また、他方の吸気口６Ｃより外側に隣接して、ＡＣ出力用コンセント６Ｅが設けられる。ＡＣ出力用コンセント６Ｅは、インバータ４０の交流出力を外部へ取り出すためのコンセントであり、表示装置１４０が接続される他、他の機器を接続して停電時の緊急電源を提供することができる。 Also, an AC output outlet 6E is provided adjacent to the outside of the other inlet 6C. The AC output outlet 6E is an outlet for taking out the AC output of the inverter 40 to the outside. In addition to the display device 140 being connected, other devices can be connected to provide an emergency power supply in the event of a power failure.
　背面扉６を筐体本体１に取り付ける場合は、筐体本体１の背面側に開口部を囲うように突出して形成されるフランジ部１Ｅ（図６）にパッキン６Ｆを当接させる。この状態でキーをキーロック部６Ａに差し込みキーを回動させると、キーロック部６Ａが回動し、フランジ部１Ｅの内側に下方向に突出する二つの突片１Ｆ（図６）とキーロック部６Ａが係合する。さらに、キーをキーロック部６Ｂに差し込みキーを回動させると、キーロック部６Ｂが回動し、フランジ部１Ｅの内側に上方向に突出する一つの突片１Ｇ（図６）とキーロック部６Ｂが係合する。これにより、背面扉６がロックされる。 When attaching the back door 6 to the housing body 1, the packing 6 </ b> F is brought into contact with a flange portion 1 </ b> E (FIG. 6) formed so as to surround the opening on the back side of the housing body 1.

　次に、上記構成の蓄電装置１００の利点について説明する。 Next, advantages of the power storage device 100 having the above configuration will be described.
　例えば、図１２に示すように、箱型の筐体Ｃに蓄電池ユニットＢを収める場合、筐体Ｃのうち蓄電池ユニットＢを挿入する側の面に下方を軸として回動自在な扉Ｃ１を設けることが考えられる。ユーザは扉Ｃ１を回動させて開けてから、蓄電池ユニットＢを筐体Ｃ内に挿入することとなる。しかし、扉Ｃ１を開けた状態では扉Ｃ１がユーザにとって邪魔となり、さらに蓄電池ユニットＢは重量が大きいため、蓄電池ユニットＢを筐体Ｃ内に挿入しにくいという問題がある。 For example, as shown in FIG. 12, when the storage battery unit B is housed in a box-shaped housing C, a door C1 is provided on the surface of the housing C on the side where the storage battery unit B is inserted so that the door C1 can be pivoted downward. It is possible. The user turns the door C1 to open it, and then inserts the storage battery unit B into the housing C. However, when the door C1 is opened, the door C1 is an obstacle to the user, and the storage battery unit B is heavy, so that there is a problem that it is difficult to insert the storage battery unit B into the housing C.
　これに対して、本実施形態の蓄電装置１００であれば、蓄電池ユニット１０Ａ～１０Ｃを始めとする各種ユニットは背面扉６を取り外すことで背面側から筐体本体１内部へ挿入する。このとき、背面扉６は取り外されているので、扉がユーザの邪魔になるということもなく、特に重量の大きな蓄電池ユニットを挿入することが容易となり、利便性が向上する。 On the other hand, in the power storage device 100 of this embodiment, various units including the storage battery units 10A to 10C are inserted into the housing body 1 from the back side by removing the back door 6. At this time, since the rear door 6 is removed, the door does not get in the way of the user, and it becomes easy to insert a particularly heavy storage battery unit, and convenience is improved.
　また、前面扉２は下方を軸として回動自在に構成されるので扉の開閉が容易であり、筐体本体１内部の各種ユニットの配線等のメンテナンス作業が容易となる。 Further, since the front door 2 is configured to be rotatable about the lower part as an axis, the door can be easily opened and closed, and maintenance work such as wiring of various units inside the housing body 1 is facilitated.
　さらに、キャスター３を設けるようにしたので、蓄電池ユニットを始めとする重量の大きい各種ユニットを内蔵する蓄電装置１００の移動を容易とする。背面側は通常、壁際に配置するが、キャスター３により背面側をユーザ側に向けるように蓄電装置１００を移動させるのが容易であり、背面側のメンテナンス作業が容易となる。 Furthermore, since the caster 3 is provided, it is easy to move the power storage device 100 incorporating various heavy units such as a storage battery unit. Normally, the rear side is disposed near the wall. However, it is easy to move the power storage device 100 so that the rear side is directed to the user side by the casters 3, and the maintenance work on the rear side is facilitated.

　次に、吸気・排気に関する構造について詳細に説明する。蓄電装置１００の一側面から見た側面図を図１０に示す。なお、図１０に示す側面と対向する側面側も同様の構成である。 <Intake and exhaust structure>
Next, the structure related to intake and exhaust will be described in detail. A side view as seen from one side of the power storage device 100 is shown in FIG. Note that the side surface facing the side surface shown in FIG.
　筐体本体１の側面にはネット状部材７が設けられ、ネット状部材７の筐体本体１内部側（図１０の紙面奥側）近傍に上方から順に、排気口１Ａ１、１Ａ２及び１Ａ３が設けられる（図１等の排気口１Ａは１Ａ１、１Ａ２及び１Ａ３をまとめて示している）。そして、図１１に示すように、排気口１Ａ１、１Ａ２及び１Ａ３の筐体本体１内部側近傍に、各排気口に対応してファンＦ１、Ｆ２及びＦ３が設けられる（図３等のファンＦはファンＦ１、Ｆ２及びＦ３をまとめて示している）。 A net-like member 7 is provided on the side surface of the casing body 1 and exhaust ports 1A1, 1A2, and 1A3 are provided in the vicinity of the inside of the casing body 1 (the back side in FIG. 10) of the net-like member 7 from the top. (The exhaust port 1A in FIG. 1 and the like collectively shows 1A1, 1A2, and 1A3). As shown in FIG. 11, fans F1, F2, and F3 are provided in the vicinity of the inside of the casing body 1 of the exhaust ports 1A1, 1A2, and 1A3 corresponding to the exhaust ports (the fan F in FIG. Fans F1, F2 and F3 are shown together).
　筐体本体１の両方の側面に配されるファンＦ１、Ｆ２及びＦ３が駆動されることにより、背面扉６に設けられる吸気口６Ｃから吸気され、両方の側面に配される排気口１Ａ１、１Ａ２及び１Ａ３から外部へ排気される。 By driving the fans F1, F2, and F3 disposed on both side surfaces of the housing body 1, air is sucked from the air inlet 6C provided in the rear door 6, and the air outlets 1A1, 1A2 disposed on both side surfaces. And 1A3 is exhausted to the outside.
　背面側は壁際に配置されることが多いので、背面側に吸気口６Ｃを設けている。これは、背面側に排気口を設けると熱が壁に当たるので、熱により壁を損傷したり、あるいは熱が壁際に籠ることにより筐体本体１内部の冷却に支障をきたしたりする、といった問題があるからである。そして、両方の側面に排気口１Ａ１～１Ａ３を設けたことで冷却性能を向上させ、特に発熱量の高い蓄電池ユニット１０Ａ～１０Ｃによる筐体本体１内部の温度上昇を抑えている。 Since the back side is often placed near the wall, an intake port 6C is provided on the back side. This is because when the exhaust port is provided on the back side, heat hits the wall, so that the wall is damaged by the heat or the cooling inside the housing body 1 is hindered by the heat hitting the wall. Because there is. Further, by providing the exhaust ports 1A1 to 1A3 on both side surfaces, the cooling performance is improved, and in particular, the temperature rise in the housing body 1 due to the storage battery units 10A to 10C having a high calorific value is suppressed.
